History
21-year-old male presents with 2 days of
nausea, vomiting, diarrhea
Day 39 s/p allogenic bone marrow
transplant for non-Hodgkin lymphoma
Acute graft-versus-host-disease

GVHD Overview
Complication of allogenic bone marrow
transplantation in which mature donor
lymphocytes attack recipient tissues (including
intestinal mucosa)
T-cells present in the graft produce inflammatory
cytokines, including TNF-α and IL-1
HLA antigens principal initiators GVHD

Epidemiology
Occurs in up to 50 % of patients who
receive an allogenic transplant from an
HLA-identical sibling
Risk factors
– HLA disparity
– Older age
– Donor and recipient gender disparity
– Splenectomy

Acute vs Chronic GVHD
Acute GVHD
Chronic GVHD
Time of onset
≤ 100 d posttransplant
> 100 d posttransplant
Target tissues
liver, skin, and GI
tract
Clinical
manifestation
Liver, skin, GI – oral
mucosa and
esophagus
Rash, skin blistering, Rash, dry/irritated
diarrhea, abdominal eyes, pain/dryness
in mouth, dysphagia
pain, nausea and
from esophageal
vomiting
involvement
Now, let’s focus on the radiological
manifestations of GVHD

Diagnosis of GVHD
Diagnosis from clinical grounds, with
radiological and histological confirmation
Severity of disease is variable
Grading determined by an assessment of
the degree of involvement of the skin,
liver, and GI tract
Stage of Acute GVHD by Organ System
ORGAN
GRADE
DESCRIPTION
Skin
+1
Maculopapular rash over <25 % of body area
+2
Maculopapular rash over 25 to 50 % of body area
+3
Generalized erythema
+4
Generalized erythema with bullous formation, desquamation
+1
Bilirubin 2.0 to 3.0 mg/dL; SGOT 150 to 750
+2
Bilirubin 3.1 to 6.0 mg/dL
+3
Bilirubin 6.1 to 15.0 mg/dL
+4
Bilirubin >15.0 mg/dL
+1
Diarrhea >30 mL/kg or >500 mL/day
+2
Diarrhea >60 mL/kg or >1000 mL/day
+3
Diarrhea >90 mL/kg or >1500 mL/day
+4
Diarrhea >90 mL/kg or abdominal pain with or without ileus
>2000 mL/day
Liver
Gut

Prophylaxis & Treatment
Prophylactic regimen a combination of
methotrexate and cyclosporine
Corticosteroids first and most effective
treatment option
One study demonstrated a 30% cure rate
of moderate to severe acute GVHD
Jaime Wilson-Chiru, HMS III
Gillian Lieberman, MD
Conclusions
Patients who undergo hematopoietic cell
transplant are at risk for GVHD
Radiological manifestations of GVHD can
look like other inflammatory and infectious
entities
Prompt diagnosis is essential, since
prognosis is dependent on early treatment
